NeuVax™ (nelipepimut-S) is the immmunodominant nonapeptide derived from the extracellular domain of the HER2 protein, a well-established target for therapeutic intervention in breast carcinoma. The nelipepimut sequence stimulates specific CD8+ cytotoxic T lymphocytes (CTL) following binding to HLA-A2/A3 molecules on antigen presenting cells (APC). These activated specific CTLs recognize, neutralize and destroy through cell lysis HER2 expressing cancer cells, including occult cancer cells and micrometastatic foci. The nelipepimut immune response can also generate CTLs to other immunogenic peptides through inter- and intra-antigenic epitope spreading. Based on a successful Phase 2 trial, which achieved its primary endpoint of disease-free survival, the Food and Drug Administration granted NeuVax™ a Special Protocol Assessment for its Phase 3 PRESENT ( Prevention of Recurrence in Early- Stage, Node-Positive Breast Cancer with Low to Intermediate HER2 Expression with NeuVax Treatment) study. The Phase 3 trial is ongoing and additional information on the study can be found at www.neuvax.com.
